Title: Lithium secondary battery and method for using it
Inventor: YAMAMOTO TAMOTSU
IPC: H01M10/058
Filed: 1993-11-09
Abstract: PURPOSE:To improve a charge/discharge cycle characteristic without decreasing electromotive force of a battery. CONSTITUTION:Li foil working as a negative electrode is divided into two parts in a condition insulated from each other by respectively providing lead out terminals 14, 15 to wind the foil opposed to collector metal foil of MnO2 working as a positive electrode, or lead out terminals 19, 20 are respectively provided in Li foils 17, 18 vertically piled through a separator 16 in a condition insulated thereby, to wind the foil in a condition opposed to the collector metal foil, so as to prepare an Li secondary battery of 3-terminal structure formed of two batteries. By this constitution, since the battery is formed in size equal to that in the past and constituted of two batteries with an electric capacity smaller by about 10%, the battery is more useful in energy to enable a number of its charge/discharge times to extend. Charging is performed by a constant current, to switch connection of the negative electrode by considering an estimated life when a charging time is decreased by 15% from the first charging.

Abstract: PURPOSE:To enable oil mist lubrication by supplying air by means of a fan, mounted on a shaft closely to a bearing, through a vent to the bearing and coupling an oil supply tube having one end communicated with the oil sump in a bearing cover to the way of the vent. CONSTITUTION:A small fan 10 for producing oil mist is fixed to the outer part of a bearing 4 for a shaft 1 closely to the bearing. Lubricant A is stored in the lower part of an outer bearing cover 5 covering the small fan 10, and a vent 11 having one end opened to the outer circumferential part of the small fan 10 and the other end opened to the inside of a rolling bearing 4 while penetrating through a bracket 3 and an inner bearing cover 6 is provided. An oil supply tube 12 having one end communicated with the lubricant 7 is coupled to the way of the vent 11. When the small fan 10 rotates to supply air through the vent 11, the oil supply tube 12 sucks the lubricant 7 and sprays a mixture of oil and air, so-called oil mist, to the bearing 4 thus lubricating the bearing efficiently.

Title: Forming method of film and manufacture of semiconductor device
Inventor: OTSUKA TAKASHI
IPC: C23C16/40
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To restrain a film from increasing in carbon compound content by a method wherein raw material that contains organic metal is dissolved in a non-polar solvent, the solvent that contains raw material is vaporized or liquidized and introduced into a reaction chamber, and a chemical reaction is made to occur for the formation of a film on a substrate. SOLUTION: A solution tank 8 is composed of a Ba-containing solution tank, an Sr-contsaining solution tank, and a Ti-containing tank, where materials Ba, Sr, and Ti are each dissolved into non-polar solvents for the preparation of toluene solutions, and the toluene solutions are each kept in the above tanks. When a film is formed by the reaction of raw material, non-polar solvent is hardly possessed of organic molecular groups of large molecular weight which coordinate around organic metal through an electric interaction with organic metal like the polar group of a polar solvent. Therefore, when a non-polar solvent is used, carbon compound introduced into a film is reduced in amount, so that carbon compound or solvent molecules introduced into a film to serve as movable ions can be lessened in content.

Filed: 1997-10-13
Abstract: PROBLEM TO BE SOLVED: To improve the dissipation efficiency of internally generated heat and for miniaturizing a case, in a closed-type communication device used for a portable telephone base station device. SOLUTION: By allowing a portion of front-surface outside of a case 10 to protrude by drawing process to provide a hollow coil-like protruding part 14, a projection is naturally formed inside the case 10 as well for increased heat-dissipation area, so that, by the amount, more internal air transmits heat to the case 10 for dissipation. Furthermore, when a fan 13 is turned on, a window is forced to flow in A direction through a coil-like path 15 of the coil-like protruding part 14 on the outside surface of the case 10, which is cooled, thus, the heat generated inside a communciation device body is dissipated efficiently.

IPC: H04Q9/00
Filed: 1987-11-06
Abstract: PURPOSE:To automatically generate subscriber data at the time of installing another terminal by transferring subscriber analysis data to all data processors on a bus at the time of detecting new transmission source terminal address information. CONSTITUTION:When a data processor 4 detects a data frame 20, transmission source terminal address information (i) is registered in subscriber analysis data 8 together with terminal address information 'A' of a data processor 2 of the transmission source because this information (i) is not registered in the subscriber analysis data 8 of the data processor 4 yet. Simultaneously, the data processor 4 transfers contents of the subscriber analysis data 8 to data processors 2 and 3 to update the contents of subscriber analysis data 9 and 10. Thus, the subscriber analysis data of data processors 2 and 3 are automatically generated at the time of installing another terminal.

Abstract: PURPOSE:To allow the output of the circuit to be outputted even when a control signal is not definite while the output is definite by providing a circuit outputting input signals independently of the control signal when the input signals are all coincident. CONSTITUTION:A data selected by a driving circuit 3 with a control signal C via a selection circuit 1 is outputted as an output 'O'.

Title: Fabrication of solar cell
Inventor: ASAI MASATO
IPC: H01L31/04
Filed: 1993-11-10
Abstract: PURPOSE:To provide a method for fabrication a solar cell in which unnecessary PN junction is not formed. CONSTITUTION:When the light receiving face of a P type substrate 21 is coated with a dopant liquid 22 by spin flow, the peripheral part on the rear of the substrate 21 is simultaneous coated with a mask liquid 23 containing titanic acid thus forming a mask liquid coating 23 only at the peripheral part on the rear side. An n<+> layer 24 (PN junction), an antireflection film 27, a rear silver electrode 28, an All electrode 29, and a surface electrode 31 are then formed sequentially. Consequently, the n<+> layer 24 is not formed in the region where the mask coating 23 is formed when it is formed on the light receiving face of the P type substrate 21. Since PN junction is not formed over the entire surface of the P type substrate 21, the step for removing unnecessary n<+> layer is eliminated and thereby the fabrication cost is reduced.
